Pythagorean fuzzy sets (PFSs) as a new generalization of intuitionistic fuzzy sets (IFSs) can
effectively handle uncertain information more flexibly in the process of decision making. As a …

Pythagorean fuzzy sets (PFSs) as a new generalization of fuzzy sets (FSs) can handle
uncertain information more flexibly in the process of decision making. In our real life, we also …

The key strategy of the three-way decisions theory is to consider a decision-making problem
as a ternary classification one (ie acceptance, rejection and non-commitment). Recently, this …

A trisecting-and-acting model explains three-way decisions (3WD) in terms of two basic
tasks. One task is to divide a universal set into three pair-wise disjoint regions called a …

Three-way decisions provide a new research perspective for solving decision-making
problems. Under a multiple-criteria environment, this paper proposes a novel decision …

Due to the effectiveness and advantages of interval-valued intuitionistic fuzzy sets (IVIFSs) in
evaluating uncertainty and risk, we introduce IVIFSs into loss functions of decision-theoretic …

As a natural extension of three-way decisions with incomplete information, this paper
provides a novel three-way decision model based on incomplete information system. First …

In order to use three-way decision (TWD) to solve multiple attribute decision making (MADM)
problems, in this article, a new TWD model with intuitionistic fuzzy numbers (IFNs) is …

Recently, some researchers have explored three-way decision models in the fuzzy multi-
criteria environments from the perspective of criterion fuzzy concept. The main …

Abstract Three-way decision (3WD) models have been widely investigated in the fields of
approximate reasoning and decision making. Recently, sequential 3WD models have …
